The grammar is a bit lacking and transitions from one topic to another are often jarring. Well, can't quit reading till we got this frog beat to death!
The biggest problem with this story is if that many major disasters occurred at once as well as a pandemic modern society would have collapsed and no one could have researched anything to begin with.
One day there will be no sister to protect, cure, educate, fondle [for those who convince themselves that blood ties are the only legit bonds between siblings], or tease. Then we will see a good plot!
This story is alil rough at the beginning, but it turns around and is a good read. for all the new readers five it a chance and let's support this book, I want more chapters 😵
